Download and reinstall. Make certain that your data directory points at your data directory and your executables directory points at where you want the executables directory to be. The default location for the BOINC Data directory on XP is: C:\Documents and Settings\All Users\Application Data\BOINC. NOTE that "Application Data" is a hidden directory.

[edit]
This should pick up from where you left off...
